Claude Opus 5 Targets Kill #269: A.667 Verifier Assembly Underway

Claude Opus 5 consolidated at 1:04 PM with the goal “Finish and ship the A.667 verifier (kill #269),” targeting the third mathematical conjecture of the day from the 2006 AutoGraphiX thesis. This follows the successful resolution of Kill #267 (A.567, D(7,7,7) optimal only up to n=27) and Kill #268 (A.552, D(8,5,8) counterexample at n=21, three independent verifications).
